The 2005 Ford F250 is equipped with an on-board diagnostics port which allows a user to connect a scanning tool and retrieve engine fault codes. This diagnostic feature can help a mechanic or owner pinpoint the cause of problems. There are several ways to obtain a code reading, from having codes read by a professional shop to purchasing a scan-tool to read codes yourself.
On-board diagnostic systems have been installed in automobiles since the mid-1990s. As cars have become increasingly computer controlled, this has allowed computer systems to report sensor or hardware failures. Codes are reported as an alpha-numeric designation, which can be read by a scanning tool. For example, a DTC (diagnostic trouble code) P0261 stands for injector low flow for the number 1 cylinder. This narrows down the problem to fuel delivery to cylinder 1, and would typically indicate a problem with the fuel injector.
A Ford dealership can scan the codes to diagnose your F250. In addition to dealerships, independent automotive shops can also provide scanning services. While shops will charge anywhere from $50 to $120 (as of 2011) for a scan of your F250, it can be a good way to get a diagnostic evaluation of problems with your truck, and be more cost-effective than simply throwing parts at a vehicle.
Many large automotive supply stores will provide a free scan of your vehicle codes. Simply stop by the store and request the free scan; an employee will bring a scanning tool out to your vehicle. While the scan is free from an automotive supply shop, they may not provide diagnosis and repair estimates.
Scanning tools have dropped in price over the years, and are now widely available at any automotive supply store. While scanner prices vary based on features, you can pick up a good scanning tool for less than $100, as of 2011. When you consider the price of a scan by a local shop, it becomes a very cost effective tool to own. In addition to scanning for engine codes, scanning tools allow you to reset the computer. Also note that many aftermarket performance tuning companies offer performance programs delivered in hand-held scanners that will scan and clear engine codes.
